To all whom it may concern:

Be it known that I, CHARLES C. MALTBY, a citizen of the United Statesof'America, and a resident.0i Cincinnati in the county of Hamilton andState of (lhio, have invented certain new and useful Improvements inLeaves or Sheets for Lo0soLeaf Binders, of which the follbwing is aspecification.

This invention relates to certain improve ments in leaves or sheets foruse. in connection with doorseflepf binders and the like, and moreparticularly, in connection with that class of binderswherein the oposite ends of the binder-back are provide with devices for engagementwith opposite ends of the binding edges of the leaves or sheets forholdin the forward andlateral edges of the [eaves or sheets in alinementwhen contained within the bind-til and of which the binder shown and,desribed in my patent pending application, Serial No. 117,939, filedAugust 1,1902,(of which the present ap lication is asubdivision) is a tvlpe and the o jectof the invention is to prev: e a leaf or sheet ofthis general character of a simple and inexpensive nature and of aconstruction adapting it for accurate en agement with said, aliningdevices of the inder-back without in any way interfering with the freeand convenient rem valor insertion of th leaf or sheet within .t ebinder and in engagement with the leaf or sheet retaining means thereof.

'l-he invention consists ,in certain novel features of this constructionof the iin )lI-fYGtl leaf or sheet whereby thesanie is ma eirjgiadll)inseriibie in and removable from the lander in and out of,enghgenientwith the Mining devices thereof andwliereby certain iiuortant ndvanta'es are attained, all as vvi he hereinafter ully setforth.

The novel features of the invention will be carefully defined in theGlttlH iS.

The improved leaf or sheet constructed according to my invention is ofan extremely aim is and inexpensive nature and is especiali; welladapted for use by reason of the uniform alinement of the edges of thesheets attained when the leaves or sheets are in lace withinthe binder,and it will be obvious mm the above description that the imgrovedleaf orsheet is ca able of some modi- 'cation without .materia departure fromthe principles and spirit of the invention-and for this reason I do notdesire to be understood as limiting myself-to the precise form andarrangement of the improved leaf or sheet herein set forth in carryingout my invention aving thus described mi; invention what I claim anddesire to secure y Letters-l atent 1.
